An Intracranial Metallic Nail Manifesting as Late Onset Epileptic Seizures / 대한간질학회지

ABSTRACT

A 32-year-old man with an intracranial nail lodged in the right temporo-occipital lobes for 21 years presented late onset epileptic seizures. His neurologic examination revealed no abnormality and electroencephalography showed only continuous slow waves localized in right temporo-occipital region. Skull X-ray showed the nail head was caught in the posterior maxillary wall and the nail body was through the temporal lobe. After removing the nail, his postoperative course was uneventful, and he has become seizure-free. The metallic nail was toxic to the adjacent brain and may have caused chronic inflammation, which may have been a cause of remote onset epileptogenesis.
